i had no sexual intercourse with my bf. but had dry humping with full clothes on 3 times. that was during my ovulation date. after 2 days of dryhumping i got my periods again that month, which was 17 days my first period on that same month with heavy bleeding. i consulted a gynaecologist and she gave some tablets for controlling blood overflow. i got no periods this month. i am really worried about that. is this any kind of effects of those tablets? what are the important causes of delayed periods except pregnancy? there is no chance of pregnancy coz we just did dryhumping and fingering. then why this delay in my periods this month.? please reply..
